WATER-METER.

Specification of Letters Patent. v .Patented Oct. 11, 1910.

Application filed January 9, 1909. Serial No. 471,532.

To all whom it may concern:

Be it known that I, JOHNB. KOELBIIJEIN,

of Milwaukee, Wisconsin, have invented a Water-Meter, of which the following is a specification.

This invention has for its object to provide a simple, cheap and effective form of water-meter for household use, one which will occupy a minimum of space and can be manufactured at a very low pricef My invention comprises in its essential elements a water-wheel having radialbuckets disposed within a closed casinghaving an inlet and outlet to and from the WheeLchamber at one side thereof, said inlet and outlet being separated by an interval somewhat greater than the spacing ofthe buckets.

Myinvention comprises further the constructions and combinations hereinafter described and pointed out in the claims.

In the drawings accompanying this speciadapted to engage under a corresponding set of retainer-lugs a formed around the edge of the open side of the casing-member A. Between the two members is inserted an annular packing-gasket C to secure tightness.

Within the circular chamber inclosed by the two members A and B is mounted the water-wheel D, which, as shown, has a cylindrical stop-ring 03 supported by spokes 0Z branching from the hub (Z and upon the periphery of thering d are mounted the radial buckets 03*. These buckets do not tightly fit the interior of the wheel-chamber, but are set slightly apart therefrom as shown at d", Fig. 5, to permit a small quantity of water to leak past.

he wheel is mounted upon a central shaft E, which turns in a bearing step e on the bottom of the casing-member B and .in

apacking-gland e fitted in a central screwthreaded opening in the top of the casingmember A, said gland confining a quantity of packing-material c to prevent leakage of water therethrough. This shaft, which is secured fast to the wheel D by a pin e may operate the usual registering mechanism, here represented conventionally by a box F containing suitable wheel trains or the like and provided with dials 7, F, f for reading the indication of the meter. The dial-box may have ears f resting upon posts f secured thereto by screws 7. Any form of registering devices may be used, and that shown therefore does not constitute an essential partof my invention.

On opposite sides of the casing A are the inlet and outlet nozzles designated respec tively a and a said nozzles being suitably threaded or provided with other means for connecting to the water-mains. Although these passages are in diametral line with the wheel-chamber, the actual inlet and outlet to the latter are at one side thereof, a construction which is carried out by the two recessed chambers a and a shown in Fig 4, which extend around to one side of the wheel- 'chamber; and the inner member B of the casing has notches or openings 5 b therein which form in conjunction with the outer casing-member A passages for the water, so that the water passes from .the inlet 81 into the chamber a through the opening 6 thence across the wheel-chamber, causing the wheel D to rotate in so doing, to the opening 6, thence along the recessed chamber a to the outleta Although two passages are open to the water, to wit around both the longer and shorter arc of the wheel-circle, the shorter arc offers much the lower resistance, and therefore by its friction passing around the edges of the 'blade gives an impulse to the wheel in the same direction as the flow of water, in comparison with which the impulse caused by any water flowing along the longer arc is negligible. The resistance to movement of the wheel itself being very low, it is found by experiment that up to a certain limit, whichv is the limiting capacity of the meter, the wheel turns at a rate practically proportional to the rate of How of water through the meter, so that the reglstering dials 7, f and i will correctly integrate the total amount which has meter. v I

In thebottom of the inner casing-member B is formed a recess 6 in which any sand passed through 'the or other solid particles carried by the water- 1 vention, and I wish it understood therefore that the latter is not otherwise limited than by the reasonable scope of my claims.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is:

1. A water-meter comprising, in combination, a casing comprising an outer and an inner member, one of which has a peripheral flange fitting within the other and forming therewith a cylindrical wheel-chamber,said flange having peripheral diametrically situated inlet and outlet apertures leading to and from said wheel-chamber and separated from one another at an angle less than 180 degrees on the circumference of said wheelchamber, a wheel mounted within said chamber, a shaft on which said wheel is secured and a registering mechanism operated by said shaft; said casing having on opposite sides of said wheel-chamber bearings inthe center of eachof its members in which said shaft turns.

2. In a water-meter, the combination of two casing-members fitting one within the other to form a cylindrical wheel-chamber and having peripheral inlet and outletpassagewa'ys, a wheel-shaft pivotally mounted in said casing-members, and a wheel mounted on said "shaft within said wheel-chamber; the inner casing-member having in the bottom thereof a depression which forms a collooting-chamber forcsolid' particles and re- 'cessed chambers extending around upon opposite sides of the wheel chamber and a rainage outlet connected with said collecting-chamber. I

3. A water-meter comprising, incombination, two casin -members which fit onewithin the other orming a cylindrical wheelchamber, the outer one .of said members having diametrally situated inlet and outlet assages, circumferential recesses in the wal s of said member communicating with said passages at one end and lying on the same side of said passages; said inner memberhaving openings in the cylindrical flan e thereof registering with the opposite en s of said recesses, said recesses forming in conjunction with the walls of said inner member and said openings therein passages leading circumferentially from said first-named passages and .openin into said wheel-chamber at a short circum erential distance from said first named passages; a shaft pivotally mounted centrally upon said casing-members, and a wheel mounted on said shaft within said chamber; said wheel having a cylindrical stop-ring at a point distant from the hub thereof and substantially extending across said wheel-chamber so that any water through the chamber must pass circularly around the same; and said wheel havin a plurality of radial buckets which nearly but not quite fill the circumferentialspace of the wheel-chamber between the ,walls thereof and said stop-ring, whereby water assing through the chamber produces an impulse acting tangentially upon said wheel.

4. A water-meter comprisin in combination, two casin -members whic fit one within the other orming a cylindrical wheelchamber, the outer one of said members having diametrally situated inlet and outlet passages and circumferential recesses in its walls communicating with said passages at one end'and lying on the same s de of said passages; said inner member having openings in the cylindrical flange thereof registering with theopposite ends of said recesses, said recesses forming in conjunction with the walls of said inner member and said openings therein passa es leading circumferentially from said rst-named passages and opening into saidv wheel-chamber at a short circumferential distance from said first-named passages; a shaft pivotally mounted centrally upon said casing-members, and a wheel mounted: on said shaft within said chamber.

- '5. A water meter comprising in combination two, casing members fitting one within the other and forming a cylindrical wheel chamber, the outer one of said members having diametrically situated inlet and outlet passages and circumferential'recesses in its wall communicating with said passages at one end and. lying on the sameside of said passages, said inner member having openings therein registering with-the op osite ends of said recesses, a shaft mounted oentrally upon said casing members, and a wheel mounted on said shaft within said chamber.

6. In a water meter,

0 two casing members fitted one within the other and forming a cylindrical wheel chamber, the outer one of said members having diametrically situated inlet and outlet passages and circumferential recesses in its walls communicating with said passages at one end and lying on the same side of said passages, said inner member having openings therein registering with the opposite ends of said recesses, said recesses forming in conjunction with the In "witness whereof, I have hre'unto set walis of said inner member aid said openmy hand this twenty-sixth day of Decemings therein passa'ges leading circumferenber, '1908.
